an interesting situation

[Sammicat]

I'm a metal vocalist...i do all those ear shattering growls and screams. I know i need to train my voice to speak higher (im a low baritone) which shouldnt be too hard because i have a 3 (and growing) octave range.
I used to be scared about transitioning and still being able to sing until i found http://www.youtube.com/watch?v=1H4SVRApGhM
Coincidentally, i wanna look like her :3 i have a very similar body type.
Anyone have any good tips around voice training for speaking?
